Answer:  32:56

Step-by-step explanation:

because first I divided 56/7=8 and then did 4*8=32. You're welcome!!! c:

is -5(x+8) equal to -5x-40 pleaseeee i need helppp

Answers

Yes.
You get this by using the distributive property.

Answer:

yes

Step-by-step explanation:

The distributive property of multiplication over additions is:

a(b + c) = ab + ac

You multiply the number outside the parentheses, the a, by each of the numbers inside the parentheses, the b and the c. Then you add the products.

Now we can do it with your example.

-5(x + 8)

We multiply -5 by x and multiply -5 by 8. Then we add the products and simplify.

-5(x + 8) = -5 * x + (-5) * 8 = -5x + (-40) = -5x - 40

A. 241 feet
B. 358 feet
C. 258 feet
D. 341 feet

Answers

Answer: A. 241 feet

Step-by-step explanation:

The figure shows two rectangular triangles.

These triangles are similar since they have two identical angles:

the first angle is 90 degrees;

the second angle is equal because the law of reflection states that the angle of incidence is equal to the angle of reflection.

The law of reflection states that the angle of incidence is equal to the angle of REFLECTION.

Let's make the proportion:

[tex]\dfrac{4}{273} =\dfrac{5}{x} \\\\x=\dfrac{273 \cdot 5}{4} =341.25 \: (feet)\\[/tex]

It takes a minimum of 100 feet for a parachute to open and safely land without injury, so:

341.25 - 100 = 241.25 (feet)

241.25 ≈ 241 (feet)

A car dealership buys a car for $12,500. They sell the car for $15,750. What is the percent markup?

Answers

Answer: 26%

Step-by-step explanation:

The formula to calculate the percentage markup is given as:

= Selling price - Cost / Cost price × 100

where selling price = $15750

Cost price = $12500

Percentage markup = ($15750 - $12500) / $12500 × 100

= $3250/$12500 × 100

= 26%

Answer: 26

Step-by-step explanation:

12,500 - 15,750= 3250
